Why powder metallurgy sintered parts is small

February 18, 2019

Powder metallurgy forming technology, most pressing forming and injection molding parts, so that the size and shape of the complex degree is limited. Powder metallurgy products have higher hardness and wear resistance, but as the shaft fatigue resistance can not be guaranteed, a small defect, it may lead to the destruction of. Powder metallurgy is unsuitable for the larger gear, the gear wheel that can transmit greater power.

Powder metallurgy sleeve with tin bronze powder as raw material, through mold pressing, sintering at high temperature after shaping. Powder metallurgy sleeve base slightly, uniform pore, the lubricating oil vacuum impregnation after the formation of oil state, having a short no lubrication, low use cost, diameter size can change characteristics.
